Conditions

Non-Muscle Invasive Bladder Cancer

Brief summary

Cohort A: Comparison of the CR rate at 6 months for patients treated with N-803 plus BCG versus patients treated with BCG alone. Cohort B: The estimate of the median DFS will be provided for each treatment group along with the 95% confidence interval. Cohort A and B: Due to the allocation of a small amount of alpha to the unplanned interim efficacy analyses, the final primary efficacy analyses will be conducted at alpha level of 0.0499.

Detailed description

Cohort A 1. Duration of CR 2. CR rate at 3, 9, 12, 18, 24, 30, and 36 months Cohort B 1. DFS rate at 3, 9, 12, 18, 24, 30, and 36 months. Cohort A 1. CR rate at 3, 9, 12, 18, 24, 30, and 36 months (all recurrent bladder cancer including low grade Ta disease) 2. Duration of CR (all recurrent bladder cancer, including low grade Ta disease).
